To all whom. t may concern.' K

Be it known that I, JOSEPH SzArnA, a cit- -izen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in `lVine Presses, of which the following is a specification.

My invention relates to a new and useful improvement in wine presses for extracting juices from fruit or the like by pressure, and has for its object to provide an exceedingly simple and effective device of this description which'may be readily adjusted for lilling, emptying or for cleansing. A further object of my invention is te provide a specially constructed receptacle or receiver for the fruit.

A still further object of my invention is to provide special means for putting a split nut into and out of engagement with the operating screw. Y

A still further object of my invention is te provide for counterbalancing the operating screw and the parts carried thereby. 2e With these ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then Vspecifically designated by the claims.

In order that those skilled in the art to which this invention appertains, may understand how to make and use the same, l will describe its 'construction in detail, referring by numerals to the accompanying drawings forming a part of this application, in which Fig. 1, is a plan view of a press made in accordance with my improvement.

Fig. 2, is a side elevation of Fi g. 1, the tub being in section.

Fig- 3, is an enlarged horizontal section at the line 3-3 of Fig. 2. i

Fig. 4:, is a detail view of the means for attaching the counterbalancing cable to the operating screw. Y

Fig. 5, is a detail perspective of the latch mechanismv for locking` the cross bar `and parts carried thereby in normal position.

In carrying out my invention' as here embodied, 1 -represents arbase upon which supported the tub 2, said tub having a series of slats 3 located upon the bottom thereof, and upon these slats is set the receptacle or cylnder 4. rI`his receptacle is made of wire gauze of sufficient strength to withstand the outward pressure of the fruit when the juice is being extracted therefrom; and as said juice is forced out of the fruit it will flow into the tub and through the places in the slate 3 to the drain pipe 5 from whence it may be conveyed in any suitable vessel. The cylinder 4l is provided with handles 6 by means of which it may he lifted out of the tub or placed therein.

l/Vithin the tub are formed the bosses 7 into which the lower ends ef the standards 8 and 9 are threaded, the standard 8 having pivoted to the upper end thereof the eress bar 10, the opposite end of said cross har carrying a head 11 in which is formed an open eye 12 for engagement with the upper end of the standard 9 when the head 1l passes between the coliar 13 and the nut let. Thislieadhasaspring actuated latch 15 the lower end of which is so formed as to engage the extension 16 formed with the collar 13 thereby locking the cross bar 10 in its normal position.

17 represents a casing or box which formed wither secured to the cross bar 1() and in this easing is housed a split nut 18; each section of said nut having an eccentric cross bar 19 passing through a suitable opening formed therein, the ends 2O of said eccentric cross bar being journalled in the side walls of the box. Upon one of the ends 20 of each of the eccentric cross bars is secured a segmental gear 21., said gears meshing together as clearly shown 'in Fig. 2, one of said segments having a handle 22 formed therewith or secured thereto so that by the manipulation of this handle the eccentric cross bars will be forced to open or close the sections of the split nut as will be readilyrv understood.

23 represents the operating screw which passes through the hub 2li formed upon the cross bar 10 and( also through the box or casing 17 and is surroni'ided by the sections of the split nut 18 in such manner that when the eccentric cross bars 19 are thrown into proper direction this split nut will engage the operating screw and be normally held in such engagement by the springs 25 set between the sections ofthe split nuts and the walls of the box as clearly shown in F The lower end ofthe operating screw 28 is swivelled to the plunger 26 by having` a liange 27 formed thereon, said flange fitting in the hub 28 formed with the plunger and and requiring the transmission o t' VYmore' f' power therethrough I provide means tor a nut surrounding said screw and threaded into said hub. By this arrangement the opera-ting screwwill be free to revolve while the plunger is held against rotation and the rotation of the operating screw is ett'ected by a spiral gear 30 which is joui-nailed in the hub 24 of the cross bar 10, said gear being splined to the operating screw as indicated at( 31. Thus when this spiral gear is rcvolve'd the operating screw will also be revolved and when the split nut is'in engagement said screw and the revolving ot the .ln practice it is intended `that the downward movement of the plunger be brought. about by the revolving oit 'the operating screw above described when the split nut is in engagement therewith since it is during this movement that it is necessary to transmit considerable power to `theplunger ior extracting juice. from the fruit within the receptacle, but by the upward movement ot the plunger should be accomplished d i'iickly .counterbalancing or slightly overbrfilancing saidplunger and the parts carried thereby'. This counterbalancing.is effected by a cable. 3G which runsover the pulleys Si and4 3S mounted upon the bracket 39, said .bracket .being secured to the pivoted' end oi the cross bar l() as indicated at 40. This-cable is attached to the upper end ot the operating screw by a disc il with which are 'formed the ears 42 having a pin passing through said ears to which the end ot the cable is attached, said disc being set in a threaded hole Orrecess del and' retained ltherein by the nut 45 which is threaded into said hole or recess the cable passing `through a. suitable hole in said nut. fr series of balls 41:6

' are interposed between the disc. and the lower end of the nut 4:5V so as to reduce the friction between these two elements' thus lpermittingthe operating screw to-revolve withoutA revolving the cable. Upon ythe opposite end of the cable `is suspendedA ,a weight 47 sniiciently heavy to countcri balance or slightly overbalance. the operating screw and plunger.

Y F rom theV foregoing description the opera.-

nacen@ tion ot my improved .press willbe obviousl as Vfollows The fruit or other material to bepressed beingplaced in the cylinder d, said cylinder is set Vwithin the tub upon the slats 3 and the plunger inserted in the upper end ,of said cylinder whenby revolving the hand wheel 34! the operating screw .will force the plunger downward within the cylinder causing the latter to exert sailicient pressure upon the i'ruit `to squeeze the `juice therefrom. iVhen Y thisV has .been accom` plished'the proper manipulationof the hand lever 29 will disengage the scctionalnut from the operating screw witliinthe plungerY and consequently the operatingy screw .be readily and quickly elevated by grasp- 1 apparatus and leaving the cylinder free Vto be removed Vfrom the tub; being-notedV that Vthe bracket swinging with theV .cross v bar l0 maintains th'e'cable'in itsproper relative position'to the op@ratingscrew.V

To reset the press Jor Vsucceeding operation it is only necessary :to placelthe 'fruit to be acted upon within the cylinder, set. latter within thev tub swing the cross bar l() back to its normal positionwhen it will be latched as beforedescribed7 manipulate the handle 22 so as-to engage the sectional nut with the operating screw and then revolve thehand. wheel 84 tofbring about the downward movement of the plunger.

Ot course I do not wishV to be limited to the exact details ot construction asherein shown as these may vbe varied within thef limits of the appendedfclaim without departing from. the spirit ot'- my invention;

Having thusY fully Vdescribed'my' Yinvention, what claimas'newand useful: is:-

A press ot' the; characteristated including an operating screw carrying a plunger1V saidV operatingscrew having a threaded recess in its upper end, a disc 'setfV in saidrecess, an vaxially bored; nut threaded into the` recess, VaY cable having ai counterbalance weight on oneend,r the other, end off-said.

cablepassing throughjthe bore of' said nut and attached. to saidV disc, and ajseries of balls interposed between the lowerendvo't the nut and said d-isc for thepurpos'e stated.
